3) Do Self Calibration:
To operate calibration, " Do Self Calibration" is selected. In order to perform proper correction, be sure to remove all
the
input signals and probe of input connector before carry out above function.
5.11. Display
1) Type (Dots/Vectors)
This selects connection mode of acquired waveform data.
Dots : Acquired waveform data are displayed on the screen only in the form of dots.
Vectors : Dots of the acquired waveform data form a line and are displayed on the screen. As dots form a line,
square waveform signal or rising edge of pulse is able to be easily observed. This is not operated in
XY format mode.
2) Format (YT/XY)
Display mode of waveform is selected by format.
YT : This is a normal type of display and shows a change of signal with the lapse of time.
XY : User compares waveforms of two channels by dots and is able to get phase difference between the
signals. Using this menu.
3) Grid (Full/Cross/Board)
This menu sets the type of measuring grid.
Full : Frame, axis and grid are all displayed. By using this scale, adjust waveform to the scale and then
measure the value of the waveform data.
Cross : Frame and axis are displayed. Cross measures a waveform by moving a waveform to the center of the
screen.
Board : Only the frame is displayed. When scale is not necessary in measuring the data value of the
waveform, or when cursor or field display is not necessary, this mode is selected.
4) Contrast Increase
Brightness of LCD is brightened by the stage of 5%.
5) Contrast Decrease
Brightness of LCD is darkened by the stage of 5%.
Push the DISPLAY button to choose how waveforms are presented
